Help Battery goes from 50% to dead in literally 2 seconds.

I've been using my Incredible 4G for about a year now. About 6 months ago, it started to randomly shut itself off for no reason. I did a factory reset, and it had been working fine since then. In the last three weeks, however, it has this obnoxious habit (happens every few days, at least) of randomly flashing the dead battery screen and shuts down, despite having a 50% or greater charge literally seconds before. It then takes 5 minutes of charging before it'll even turn back on.

I've tried taking my battery out and cleaning both it and the phone thoroughly, but it hasn't seemed to make a difference. I was wondering if other people have had this problem, and if so what you did to fix it? I'm guessing the next step is to replace either the battery or the phone, but I'm not sure which the problem is with. Any help would be appreciated! Thanks.

Sounds to me like a bad battery. It could be shorting as it discharges (there's a defect caused by a speck of dirt getting into the battery during manufacture) or it could be that you discharged it too far too often. (You should try to charge it when it gets down to 40%-60% of charge for longest life.)

Thank you! I will try replacing the battery, then. I appreciate the tips!
